A 12" lateral Polyvinyl chloride (PVC) connection will service the I onsite fire system, originating from an existing 12" water line running below Gazelle Court. The fire line connection will utilize one 12" double detector check valves (DDCV). The connection services an onsite looped fire system consisting of a 12", a 10", and an 8" line that will serve the I fire sprinkler connections and six separate hydrants around the site. I CRITERIA AND METHODOLOGY The modeling of the onsite fire service lines was completed using the EPANET 2.0 program (EPANET). Usage of the water and sewer plans provided the scaled distances for the project. I The schematic used in EPANET can be found on Attachment 1. I Head Loss Across Fittings Minor losses encountered in the Ductile Iron Pipe (DIP) fittings along the pipelines were neglected in the model (i.e. elbows, tees, etc.). The headloss (HL) across the backflow apparatus I was addressed and modeled using the method described below. The Watts 12" double check detector assembly (DCDA) was modeled as a general purpose valve I (GPV) in series with a check valve. The HL curve can be found on the specification sheet for the Watts DCDA on Attachment 2. This information was used to develop Figure 1 below, which displays the HL curve created for usage in EPANET to model the flow within the system. I Additional information for the proposed backflow device can be found on Attachment 2.

Modeled Demand Flows To ensure the onsite hydraulics can supply adequate flow to the system during a fire event, Excel Engineering tested a primary and secondary scenario. The 2016 California Fire Code (CFC) refers to Appendix B to obtain fire-flow requirements for buildings. Using Table B105.1, it was determined that the type IlIB, 144,500 square foot building would require a fire-flow of 8,000 gallons per minute (gpm). By providing the building with fire sprinklers, the required flow can be reduced by 75 percent and results in a required flow of 2,000 gpm. For the purposes of this report, the flow was only reduced by 50 percent to 4,000 gpm. The calculated fire-flow system criteria enabled the following scenarios to be tested: Scenario 1 - For this scenario, a demand of 4,000 gpm was supplied to the system and distributed between two hydrants furthest from the onsite connection, one hydrant located near the loop connection point, and no flow was provided to the building. Scenario 2 - For this scenario, a demand of 4,000 gpm was supplied to the system and distributed between the two hydrants furthest from the onsite connection, one hydrant located near the loop connection point, and a flow of 500 gpm was provided to the building. I I I I I I [1 I I I I I I I I I I I I I I I I 1 I I I I I I I I I I Tie-In Pressures Available Existing flow and pressure data from the public system in Whiptail Loop East was taken from a flow analysis performed by the City of Carlsbad Fire Department (CCFD) on 01/17/2017. To model this scenario in EPANET the pressure available was modeled as a reservoir with a total head equivalent to the Static Pressures given in the analysis provided by the City. This pressure test data can be found on Attachment 3 to this report, and is summarized in the table below. Table 1: CCFD Flow Test Results Hydrant NO Static Static Elevation (ft) Total Head Reservoir Pressure (psi) Pressure Available Number (ft of head) (ft) 134 309 377 686 1 CALCULATONS AND CONCLUSIONS This performed analysis confirms that the underground fire distribution system will provide fire flows to the site for Scenario 1 and Scenario 2 given the following parameters: Minimum residual pressure for the project shall be 20 pounds per square inch (psi) during fire flow demand. Pipe velocities shall not exceed 10 feet per second (fps). The velocity and pressure results for this project are discussed below. Scenario 1 For this scenario, the highest velocity found in the system was in multiple pipes. This velocity was recorded as 11.35 fps. See Attachment 4. Minimum Pressure - For this scenario, the minimum pressure in the system is found in Junction 33. The recorded pressure was 107.0 psi. See Attachment 5. A velocity of 17.02 fps was found in the pipes leading to the hydrants (Pipe 22 and 12) for this scenario. Scenario 2 For this scenario, the highest velocity found in the system was in multiple pipes. This velocity was recorded as 12.77 fps. See Attachment 6. Minimum Pressure - For this scenario, the minimum pressure in the system is found in Junction 33. The recorded pressure was 103.4 psi. See Attachment 7. A velocity of 17.02 fps was found in the pipes leading to the hydrants (Pipe 27 and 25) for this scenario. 3 I I I I I I I I I I I I I I I I I I I Site Schematic Existing 770 Zone 12" pvc in Gazelle Court / Junction #35 Flow = 1,000 gpm (both scenarios) Existing Hydrant On 16" PVC water line in 770 zone (see fire flow test) / Junction #33 / Flow = 1,500 gpm / (both scenarios) Junction #31 Flow = 500 gpm (scenario two) / Junction #32 / Flow = 1,500 gpm / (both scenarios) ru ES-774DCDA Job Name ______________________________________ Contractor Job Location Approval Engineer Contractor's P.O.
